Issue 3 of JAAS now online!

JAAS issue 3 is now available online.

The front cover of this issue features work by Frank Vanhaeke and colleagues from Ghent University and Janssen Research & Development, Belgium.  They use laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) for assessing the distribution of a novel anti-tuberculosis compound containing bromine and its metabolites in rats.  Compared to the traditional radioluminography technique, the LA-ICP-MS method does not require labelling of the drug compound with a radionuclide.

A pilot study on the use of laser ablation-ICP-mass spectrometry for assessing/mapping the distribution of a drug and its metabolites across the body compartments of rats, Andrei Izmer, Deepti Gholap, Kathleen De Houwer, Filip Cuyckens and Frank Vanhaecke, J. Anal. At. Spectrom., 2012, 27, 413-418

The inside front cover highlights work by R. Escobar Galindo and co-workers from Spain and Luxembourg, who report the in-depth multi-technique characterisation of chromium-silicon mixed oxides produced by reactive ion beam mixing of the Cr/Si interface.  There is a great deal of interest in mixed metal-silicon oxides due to their suitability for a variety of applications, including as optical coatings with an adjustable refractive index.  The authors employed a variety of techniques to look at the in depth composition and concentration profile of these materials.

In-depth multi-technique characterization of chromium–silicon mixed oxides produced by reactive ion beam mixing of the Cr/Si interface, R. Escobar Galindo, N. Benito, D. Duday, G. G. Fuentes, N. Valle, P. Herrero, L. Vergara, V. Joco, O. Sanchez, A. Arranz and C. Palacio, J. Anal. At. Spectrom., 2012, 27, 390-400

JAAS Issue 2 now online!

JAAS, Issue 2, 2012, front coverIssue 2 of JAAS for 2012 is now online!

The front cover this month features work by Magdalena Szczerbowska-Boruchowska and colleagues from the AGH University of Science and Technology and Jagiellonian University, Poland.  They present a synchroton radiation micro-X-ray absorption near edge structure study of sulfur speciation in human brain tumor cells.  The authors looked at both the experimental and methodological aspects of 2D imaging of sulfur species in tumor cells, and developed procedures to eliminate disrupting effects in the imaging distribution.

JAAS, Issue 2, 2012, inside front coverThe inside front cover highlights work by Michael Krachler and Detlef  Wegen from the European Commission-Joint Research Centre in Germany, on the promises and pitfalls in the reliable determination of 233U using high resolution ICP-OES.  They show that the current analytical approach for determining 233U at λ = 385.950 nm is not specific to that particular uranium isotope for reliable quantification.  The authors show instead that analysis at λ = 411.585 nm is potentially a better option for reliable determination of 223U using HR-ICP-OES.

This issue of JAAS also features…

…the Atomic Spectroscopy Update by Owen Butler and colleagues – the 27th annual review of the application of atomic spectrometry to the chemical analysis of environmental samples:

Atomic spectrometry update. Environmental analysis, Owen T. Butler, Warren R. L. Cairns, Jennifer M. Cook and Christine M. Davidson, J. Anal. At. Spectrom., 2012, 27, 187-221

Quantitative analysis of branched amino acids in a single fruit fly

Japanese scientists have used a highly sensitive and accurate analytical method to determine the quantity of free branched amino acids (BCAAs) in a single fruit fly.

Fruit flies are a valuable organism in biological research, and particularly in the areas of genetics and developmental biology.  However, as these creatures are small, analysing the metabolites in its body is difficult, and generally a large sample pool is required.  However, this means that small individual distinctions are lost and the fly’s aminogram is equalised.

By using liquid chromatography-inductively coupled plasma-mass spectrometry (LC-ICP-MS) with pre-column derivatisation with a metal tag reagent, Daigo Iwahata and colleagues managed to accurately analyse the quantity of free BCAAs in a single fruit fly.
